Applications and features

Applications:

  • Double prongs are suitable for traditional insulated sandwich panels, comprised of a thin fascia wythe, insulation and a much thicker structural wythe.
  • This system is designed to create a non-composite insulated concrete sandwich panel.
  • It can be used anywhere where you need to tie the two wythes of concrete together with a non-conductive wall tie but it will still allow the two layers to shrink or expand independently of one another using the tie for deflection.

Features:

  • Holds a face wythe of concrete affixed to the panel without the need for thermally inefficient metal connectors or solid concrete sections.
  • High strength and low thermal conductivity.
  • High-performance, alkaline resistant, engineered thermoplastic.
  • In-place temperature range: -40°C to 93°C.
  • Standard non-composite ties are available as double prong or standard tie.
